Well, it appears you’re on windows using ruby 1.8.6 with rails 2.3.8
(and
apparently have at least two plugins: one named open_flash_chart_2 and
resque)…

RESQUE CONF {“production_private”=>“localhost:9878”,
“auth”=>{*****}, “development”=>“localhost:6382”,“test”=>“localhost
:6379”, “staging”=>“localhost:6379”}

Yeah, you really ought to make a habit of scrubbing things like username
and
passwords out of any data you copy/paste into a post. Perhaps they’re
throw-away, dev. machine-only credentials. Even if they are, good
security
habits will protect you…

bignum too big to convert into `long’

I certainly hope you Google’d: “bignum too big to convert into long”
first.
I’ll assume you did and looked at the results (that aren’t your own
post).
If your then actually look at the top of your stack trace (which it’s
awesome you provided):

c:/Ruby186/lib/ruby/site_ruby/1.8/rubygems/requirement.rb:109:in `hash’

The innermost scope is clearly within the “requirement.rb” file (line
109)
of rubygems itself. So, add “rubygems” to your error phrase in
Google…
Anyhow, that’s what I did. I immediately found some posts that, though
people had a slightly different setup/problem/environment, they all
seemed
to point to the problem being a bug in old versions of rubygems.

What version of rubygems are you using? I’m guessing its the version
bundled
with the 1.8.6 windows installer which I’m guessing is 1.3.7? If I’m
right
then this is an old version so perhaps you need to upgrade your
version up
rubygems? If this is the case, you’ll also need to upgrade to a newer
version of ruby because rubygems 1.3.7 is the newest version that
supports
ruby 1.8.6.

So, I’m my guess (it is just a guess) is correct, you really ought to
attempt to install ruby 1.8.7 (which should come with the latest
rubygems)
and use it to run your rake task.
